The date February 16, 2018 marked 5000 Martian sols since the Opportunity rover landed on Meridiani Planum on January 25, 2004. The solar-powered Opportunity rover initially had a 90-day prime mission and was not expected to survive its first Martian winter. Eight Martian winters (14 Earth years) later, the rover has driven 45 km (28 mi) and has returned over 225,000 images of the Martian surface. Opportunity is continuing to explore Perseverance Valley, a channel within Endeavour Crater.
